Problems solved by technology

Most of the puncture needles currently on the market have beveled needles, which are easy to deviate from the target when puncturing, thereby causing other tissues or organs around the puncture site to be punctured, thereby causing danger; moreover, most of the existing puncture needles are single-lumen. The extraction of effusion and the injection of drugs share the same cavity, which is easy to cause cross infection during use; although some double-lumen puncture needles have appeared, the suction cavity and injection cavity on this double-lumen puncture needle The road is fixedly connected with the puncture needle body, and different drugs cannot be injected at the puncture site during use; in addition, the existing puncture needles are not easy to store and carry

Abstract

The invention provides a medical puncture needle. The puncture needle comprises a syringe, a puncture needle body slidably connected to the syringe, and a push rod detachably connected to the punctureneedle body; the syringe needle of the puncture needle body is set as a three-diamond shape; two positioning blocks are arranged at symmetrical positions on both sides of the needle body of the puncture needle body; the two sides of the syringe are provided with sliding grooves which are slidably connected with the positioning blocks to guide and position the puncture needle body during the puncture process. The medical puncture needle is simple in structure; the syringe needle of the puncture needle body is set as the three-diamond shape, and guide components are arranged, so that precise puncture is realized, thereby ensuring the safety of the operation process.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a medical puncture needle. Background technique [0002] The puncture needle is a medical device for sampling and injecting tissue from various organs such as the kidney, liver, lung, breast, thyroid, prostate, pancreas, testis, uterus, ovary, and body surface during minimally invasive surgery. Most of the puncture needles currently on the market have beveled needles, which are easy to deviate from the target when puncturing, thereby causing other tissues or organs around the puncture site to be punctured, thereby causing danger; moreover, most of the existing puncture needles are single-lumen. The extraction of effusion and the injection of drugs share the same cavity, which is easy to cause cross infection during use; although some double-lumen puncture needles have appeared, the suction cavity and injection cavity on this double-lumen puncture needle The channel is fixedly ...
